R-Rated Series - Medium Voltage Fuses

R-Rated Fuses
       
R-rated fuses provide required short-circuit protection for medium voltage motors, motor controllers and associated circuitry. These components have limited ability to absorb the energy of large short circuit currents. Medium voltage motor controllers contain overload relays which provide both overload protection and locked rotor protection to the motor. The controllers are also intended to interrupt low value short circuits within the capability of the motor controller. This protects the medium voltage R-rated fuse from sustained overcurrents which are less than their minimum interrupting rating.

NEMA Standards for R-rated medium voltage power fuses require that they operate within 15-35 seconds when subjected to an rms current 100 times the 'R' rating. For example, a fuse with a 2R rating will open within 15 to 35 seconds on an applied current of 2 x 100 = 200 amperes.

Options

  • Hermetically sealed for use in hazardous locations (add “S” suffix to part number)
  • Bolt-in mounting configuration. For hookeye attachment; add ‘W’ suffix to part number.

Live Parts

Live parts and mounting clips are available for mounting R-rated single, double, and triple barrel fuses. Note, all clips are sold in pairs.
